Consider penicillin for a moment, would one have heard of penicillin resistant strains of bacteria before the discovery of this wonderful drug? No, of course not, so how else could we but by evolution? It is a never ending battle between modern medicine and the inherent variability of microbes(Quammen). A prime, although tragic, example of this is HIV. After just a few years of infection and drug treatment, each and every individual with HIV carries a unique version of the virus(Quammen). Another instance in which we can see evolution is through a process called Artificial Selection. Artificial Selection is the process in which humans have created, or, rather, bred, something instead of nature. Humans obviously select traits that serve them best and are not necessarily to the advantage of the creature being bred were it in the wild. A prime example of Artificial Selection is the breeding of dogs. Descended from wolves, as the reader hopefully knows, dogs are now incredibly varied in their traits, which allows for selection based upon one’s desires. Humans, over many thousands of years, selected different traits in canines that they deemed desirable for one reason or another and bred the animals in such a way that these traits became
